Description

[Detailed description of the invention]

0001

[Field of Industrial Application] The present invention relates to a data processing device for storing and editing data such as a series of documents, images, etc.
In particular, the present invention relates to a screen positioning function suitable for efficiently displaying target data from a series of data on a screen using a word processor or the like.

0002

[Prior Art] Regarding the conventional screen display positioning function, the image displayed on the CRT is one screen before, one screen after,
There is a function to display a desired image by selecting a few screens forward or several screens backward, a high-speed page turning function, and specifying an absolute position.

[0003] When a user displays desired data on a screen, these functions are combined to detect the desired data.

0004

[Problem to be Solved by the Invention] However, these conventional functions cannot display the desired data on the screen from among the large amount of data recorded in a format that allows the user to judge the context. No consideration was given to efficiency when attempting to search.

[0005] Generally, when editing a large amount of data using a word processor or the like, the user understands the context of the recorded data as a series, such as files or stories arranged by date. There are often When you search for specific data from data with these characteristics and try to display it on the screen, you can tell whether the data is in front or behind the current display position, In many cases, the absolute position is unknown.

[0006] Conventional display positioning functions do not take into consideration the efficiency of searching data while using the screen display function for such purposes, and it is difficult to search by displaying the screen in small increments. , it was necessary to check and specify the absolute position in all data in some way, or to search using a combination of these.

[0007] An object of the present invention is to enable efficient search processing using such a screen display by utilizing the user's judgment of context.

[0008]

[Means for Solving the Problem] The above object is to provide a screen display positioning function that, while some screen display positioning function is continuously instructed (hereinafter referred to as surface positioning mode), Ability to keep the most recently viewed position in the background. and the most recently displayed position in the front and rear according to the forward positioning instruction and the backward positioning instruction, respectively;
This is achieved by providing a function for directly positioning the screen at an appropriate intermediate position between the current display position and displaying it on the screen. Hereinafter, these display positioning methods will be referred to as forward positioning and backward positioning, respectively.

[0009]

[Operation] In states other than the screen positioning mode, the most recent forward and backward screen display positions have the values of the beginning and end of the stored series of data, respectively.

[0010] When a user attempts to display target data while searching for it, it is determined whether the data is located relatively before or after the currently displayed position.

If it is in front, select the forward position display function. This changes the screen display position to a position midway between the beginning of the series of data and the current display position. Furthermore, it is determined whether the target data is before or after this new display position, and if it is behind this new display position, the backward positioning display function is selected. The screen display position at this time is between the previous display position and the current display position.

[0012] By repeating this operation, the range to be searched is reduced by half in one operation, and the target screen can be searched more effectively than displaying and searching one screen at a time.

[0013]

[Embodiment] Hereinafter, one embodiment of the present invention will be described in detail.

FIG. 1 is a block diagram showing the configuration of a document creation device according to the present invention, and FIGS. 2, 3, and 4 show one implementation of a processing procedure when the present invention is applied to the document creation device shown in FIG. This is an example. FIG. 5 is a diagram showing changes in the display position when data is searched using the function according to the present invention.

In FIG. 1, 1 is a storage device that stores document data, etc., 2 is a processing device that processes document data,
3 is a display device for displaying the data being processed; 4 is an input device for instructing editing and other processing.

Among the input devices, 5 to 7 are input devices for selecting screen display positioning functions. 5 is a selection instruction for a conventional screen display positioning function, 6 is a selection instruction for a forward positioning function, and 7 is a selection instruction for a backward positioning function.

The fact that functions 5 to 7 have been selected is transmitted to CPU 8. Document data is stored in one storage device in display units of one screen. 8 CPUs have a pointer indicating a position on the storage device, 10 a forward pointer, 11 a backward pointer as a function of holding the most recently displayed position, and 12 a display pointer.

The position indicated by the 12 display pointer is displayed on the 3 display device as document data.

Hereinafter, according to the flowchart of FIG.
, 3, and 4 will be explained.

First, when the process is started, forward pointer 10 and backward pointer 11 are set at the beginning and end positions of the document, respectively. (Step 100).

[0021] The 8 CPUs receive input from 4 input devices (
Step 200). When an input is made, it is determined whether the input is an instruction for the screen display positioning function 5 to 7 (step 300). If the instruction is for something other than the screen display positioning function, the process instructed by the input is performed and the process goes to step 100 (steps 310, 320).

In step 300, if the selected function is the screen display positioning function, the following step 40 is performed.
Processed from 0 to 1140.

If the forward positioning function is selected according to the selection instruction of 6 forward positioning (step 400), then 11
Set the backward pointer to the position indicated by the 12 display pointer (step 410), set the 12 display pointer to an intermediate position between the 12 display pointer and the 10 forward pointer, display that on the screen, and jump to step 200 (step 420). .

Similarly, if the rear positioning function is selected by the 7 rear position selection instruction (step 50
0), sets the 10 forward pointer to the position indicated by the 12 display pointer (step 510), and sets the 12 display pointer to 1
It is set at an intermediate position between the 2nd display pointer and the 11th backward pointer, the position is displayed on the screen, and the process jumps to step 200 (step 520).

[0025] Furthermore, if another screen display positioning function is selected, if the display is one screen ahead (step 600).
, the value of the 11 backward pointer is changed to the value of the 12 display pointer (step 610), and then the value of the 12 display pointer is changed to the value of the previous screen and displayed (step 620).

If it is one screen behind (step 700), 1
After setting the value of the 1 forward pointer to the value of the 12 display pointer (step 710), the value of the 12 display pointer is set to the value of the next screen and that screen is displayed (step 720). If the first display of data is selected (step 80
0), after setting the value of the 10 backward pointer to the value of the 12 display pointer (step 810), the 11 forward pointer,
12 Set the value of the display pointer to the first value of the series of data,
It is displayed (step 820). If the last display of the data is selected (step 900), the value of the forward pointer 11 is set to the value of the display pointer 12 (step 910), and then the values of the backward pointer 10 and the display pointer 12 are changed to the value of the 12 display pointer. Make it the last value and display it (
step 920). If the absolute position display function is selected (step 1000), if the position is ahead of the position indicated by the 12 display pointer, the value of the 11 backward pointer is set to 1.
After replacing the value of the 2 display pointer with the value of the 12 display pointer, set the value of the 12 display pointer to the position specified by the absolute position display function and display it there (steps 1100 to 1120
).

If the position is behind the position pointed by the 12 display pointer, replace the value of the 11 forward pointer with the value of the 12 display pointer, and then set the value of the 12 display pointer to the position specified by the absolute position display function. and displays it (steps 1100 to 1140).

Next, an example of data retrieval using the functions of the present invention will be shown using FIG. Document data is stored in 1 storage device.
The data is recorded in 16 pages as shown in the arrangement of 5 screen data.

Now, suppose that the user wants to search for data on the twelfth page after the current position while the fourth page is being displayed on the screen, but does not know the desired page position.

[0030] If the conventional screen display function is used, it is necessary to search sequentially using the backward function in the steps 15a to 15h in the lower row.

When using the functions of the present invention, first, by using the backward positioning function, the display position can be changed from 15i to 15
It will be in position j. Since the target data is further backward, if the backward positioning function is used again, the next display position will be the 15k position. At this position, the target data is in the front, so if you use the forward positioning function,
There are now 2 pages, and the desired data can be searched and displayed in 4 times, compared to 9 times with the conventional function.

[0032] In the above embodiment, the position corresponding to exactly one-half is displayed as the midpoint, but this can be divided by any value, and the position can be specified using each value.

Furthermore, the unit for determining the display position is not limited to the display screen, but may also be a series of data, images, or other information contained therein.

Further, any input device and instruction method including a keyboard, an icon, etc. can be used as the input device 4, the forward positioning function selection instruction 5, and the backward positioning function selection instruction 6.

[0035]

[Effects of the Invention] As described above, according to the present invention, when searching and displaying target data from a large amount of data that has a series of contexts in the user's consciousness, You can search and display only the context of the current location without having to be aware of the absolute location.

Furthermore, when searching for an arbitrary screen from the top of n screens, approximately n/2 operations are required using only the function of displaying one screen before and after, but with the present invention, the intermediate point can be If it is set to 1, the desired screen can be displayed in approximately log2 n operations.
